Social content features based on user tracking

ABSTRACT

Prioritizing online comments on social network web page is disclosed. An activity of a user consuming a content presented on the social network web page is detected. Time spent by the user consuming the content is determined. Responsive to the user entering a comment on the content, a depth of consumption of the content by the user is determined based on the time spent by the user consuming the content. The comment entered by the user is ranked among a plurality of comments entered by one or more of the plurality of users based on the depth of consumption. The comment entered by the user is presented on the social network web page in the order of the ranking.

FIELD

The present application relates generally to computers and computer applications, and more particularly to social networking and computer-implemented application that identifies and prioritizes user comments on online social network.

BACKGROUND

Social networking applications allow users to post content on their social network application page and also to view and comment on the content posted by other users of the social network application. It has been found that not all users actually read or view the online content about which the users are making comments. For example, users may indicate their likes or post commentaries on a content shown on their social network pages without having read the content. In this context, not everyone's voice is equal. That is, people may spend a lot of time reading and considering materials, only to have their voice drowned out by the opinions of consumers who have not really considered a topic. Equally, the readers and consumers of the comments, shares, likes, are themselves at a disadvantage, not receiving the most thoughtful or relevant information.

BRIEF SUMMARY

A method of prioritizing online comments on social network web page, in one aspect, may comprise detecting an activity of a user consuming a content presented on the social network web page. The method may also comprise determining time spent by the user consuming the content. The method may further comprise storing the determined time spent by the user consuming the content in a data structure associated with the user, wherein the detecting an activity of the user, the determining of the time spent by the user, and the storing are performed for each of a plurality of users. The method may also comprise indexing the plurality of users' time spent consuming the content. The method may further comprise, responsive to the user entering a comment on the content, determining a depth of consumption of the content by the user based on the determined time spent by the user consuming the content. The method may also comprise ranking the comment entered by the user among a plurality of comments entered by one or more of the plurality of users based on the depth of consumption. The method may further comprise presenting the comment entered by the user on the social network web page in the order of the ranking.

A system for prioritizing online comments on social network web page, in one aspect, may comprise a processor and a memory coupled to the processor. A user interface associated with a social network application running on the processor presents a content; and an application running on the processor detects an activity of a user consuming the content presented on the user interface.

DETAILED DESCRIPTION

A method, system and/or techniques are provided that prioritize or rate user's online comments based on the user attention paid to the online content or material relevant to the comments. In one embodiment, users viewing of content may be tracked to form a viewing time by entries (e.g., elements, sections) in the content for individual users and comments from the users related to the content are prioritized based on a user attention (e.g., time spent) on the entries related to the comments. In one aspect, the user attention is derived from data points considering display of the entries of the content and other displayed content. The comments may include “liking”, “disliking”, “sharing”, “posting” and/or others. “Liking” of content on a social network user interface page, for example, indicates the user's approval of the content. “Disliking” of content on a social network user interface page, for example, indicates the user's disapproval of the content. “Posting”, for example, allows inputting a descriptive commentary on the content via the social network user interface page. Such comments may be entered on a user interface page of the social network application, e.g., the user's social network web page, by clicking on one or more user interface elements such as buttons, inputting text or pictures, or another media. The content may include text, video, audio, images, and/or others. In one aspect, the attention is prorated based on user specific behavior. The prioritized or rated comments may be displayed ordered by the priority. The entries related to the comments may be determined by an algorithm that factors counts of references, attributions, subject relevance and combination of words.

The method, system and/or techniques of the present disclosure in one embodiment prioritize and display comments and/or shares of user who have more thoroughly considered the material being shared. In one embodiment, the method and/or system may track the length of time a user has spent reading, e.g., an area of content (e.g., an online article) a user has read or area of a video the user has viewed may be tracked noting the amount of time or effort the user puts into the reading or viewing. In one aspect, responsive to the user (e.g., a reader) taking an action on the content (e.g., liking, sharing, messaging, commenting), the method and/or system may use the information about the user's reading of the article to improve the rendering of feeds for people following the commentator (the user) in a number of ways by computing a relevancy score for the user's action.

The method and/or system of the present disclosure in one embodiment may include utilizing user tracking to determine how long a user spends reading content, and using this information to promote actions of a user who has absorbed the material to their followers. In this way, a consumer of a news feed sees the most thoughtful and considered comments and actions from the consumer's network. User's comments and actions for display to the user's network are weighted based on how long the user spent reading the content. In one aspect, emphasis is given to those users that spend more time reading the content. By utilizing social content features based on user tracking, better feedback and recommendations into the social network may be obtained.

In one aspect, the method and/or system of the present disclosure may use existing technology such as embedded browser controls and mobile apps (applications) to gather how long a user spends reading a particular content, e.g., online newspaper article, short story, post, or another online content. This knowledge is input into a social network for intelligent suggestions for future readings. Responsive to a user commenting on content the user has read or, in the case of a video, viewed, the method and/or system can treat the user's comment differently than a comment from someone who has not read the content.

In one embodiment, actions from users who have actually read the article (e.g., as measured by a progression at least of a certain speed through the article, where the threshold speed may vary by reader based on their history) or viewed a video (as measured by the video playing through to completion) are given a higher score. If the user has quoted a specific area of the article, the method and/or system of the present disclosure in one embodiment confirm that the user has read that area of the article or watched that part of a video in context (e.g., as opposed to viewing a clip selected by another user or copying a quote from another user). If the user has not read or viewed the area being quoted, the score for the user is lowered.

FIG. 1 is a flow diagram illustrating a method of detecting a degree of user attention paid to social content and prioritizing social content features in one embodiment of the present disclosure. For instance, the method may prioritize comments based on user attention to material relevant to the comments, for example, on social network web page. At 102, a user activity on content (online content) is detected. For example, a user's consuming of content via a user interface of a social network (or the like), for instance, reading content, viewing video, listening to audio, or performing another activity on a user's social network page, is detected.

At 104, time spent reading or otherwise consuming this content, e.g., which sections have been on the screen for certain time, which sections of video or audio have been consumed, is determined and saved for the user. Various existing techniques may be used for capturing this information. An example includes explicit third-party information sharing, which may include various forms of front-end cross domain information sharing or backend database merges. Other examples may include an application or browser provided by a social network application, such as embedded controls in a social network application, plugins in the browser, and a mobile application using an embedded browser to display content which is linked to from inside the application. Even when those options are not available, the system and/or method of the present disclosure may track when the user has at least clicked on the content, and use that information to promote the user's actions and comments on that content. The system and/or method of the present disclosure may also make use of embedded audio and video controls and content readers to keep the user's actions in view of the social network where possible. In one aspect, based on the tracked information associated with the user's viewing of the content, a viewing time data for each user may be generated and stored. For instance, the viewing time data may be organized or structured according to a viewing time data structure that includes viewing time entries by element or section of the content for each user. The viewing time data may be stored in the viewing time data structure.

At 106, one or more data points are used to determine time spent on an article. A data point for example may include a point in data operation such as when a browser window for the content was opened/closed (e.g., in the case that more specific tracking is not available) or how long it takes for the user to return to the social network after clicking an external. For instance, when a user content view is not in direct view of the system, such as when a user opens a link from the user's social network application in an operating system and browser that does not integrate or does not have a plugin for the social network, and where the target of the link directs to a web site or another online location, which does not share information with any third parties, the system and/or method of the present disclosure in one embodiment may estimate the time spent in the other web page (or another online page) based on the user's return time back to the user's social network page. In one aspect, if there is absolutely zero return time, it may be assumed the user has opened the material for later consumption and such zero return time in one embodiment is not be counted against the user, e.g., it is counted differently from 0 reading time.

At 108, times from all users (e.g., users who have commented on this content so far) are gathered and indexed according to the material and time spent on each area of section of the content. For instance, the processing at 104 and 106 may be performed for each of a plurality of users that are consuming the content on their respective social network web pages.

At 110, each user's consumption time for the content (e.g., text, video, other media) is normalized according to past behaviors of the user, e.g., to ensure that faster readers or viewers are not penalized.

At 112, responsive to the user entering a comment on the content, the user's depth of consumption of the content may be identified based on the user's time spent reading or viewing the content, for example, determined at 104.

In one aspect, for example, as shown at 114, responsive to the user commenting on the content, the user's comment is scanned for references to the content, e.g., if the content included an article, for references to the article. For example, the section of the content the comment addresses or references may be determined. Such references in the user's content may be explicit, direct references such as quotes, and/or uncommon combinations of words which appear disproportionately in the user's comment compared to the normal vocabulary of the user, and which also appear in certain section of the content text disproportionately to the rest of the content text, where content text may be an automated transcription from audio or video. For instance, if the user's comment contains the words “XYZ”, and the article contains “XYZ” in numerous places throughout the article, then the attribution to a specific area of the article is not determined. However, if the article only mentions “XYZ” in one paragraph or one section of video, and the text does not appear in summary information about the article such as a description or tags (e.g., descriptive tags associated with the article or content, metadata associated with the article or content), then the user's comment is taken to be related to a specific area of the content.

At 116, the referenced section is compared to the indexed consumption recorded for the user, e.g., to determine whether or not the user has consumed the content and/or the depth or degree of the user's consumption. If the user has not clicked on the link through the social network application or page, but is taking a reshare action with a comment from another user's share, then the system of the present disclosure in one embodiment concludes the user is commenting without reading. If the user has clicked on the link, the system of the present disclosure further determines the depth of the user's consumption, and whether the user has consumed the area being discussed. The depth or degree of the user's consumption is determined to be proportional to the amount of time spent by the user reading or viewing the content or the area of the content.

At 118, comments and/or other actions (e.g., reshares) are prioritized for delivery to followers based on whether the user (actor) actually consumed the content being acted on, the depth to which they consumed it, and the depth relative to their normal level of contribution. For instance, the user's comment is ranked among a plurality of comments entered by one or more other users based on the depth of the user's consumption. The user's normal level of contribution may be determined as an average or mean level of the user's contribution history on the user's social's network.

In one aspect, there may be cases where the system's determination may be inconclusive. For example, a user's action may direct viewing of content that is outside the view of the social network application. In one embodiment, the system and/or method of the present disclosure may treat such cases as if the user has consumed the content. In another embodiment, the system and/or method of the present disclosure may be configured to give preference to the users whose viewing behavior is known to the social network.

At 120, the comment entered by the user is presented on the social network web page in the order of the ranking. For example, comments from users with a greater “reading time” are prioritized during display. For instance, comments on content item on a social network page may be displayed in the order of prioritization, for example, the user's comments may be displayed in a ranked order among other users' comments, for example, with the comment determined to have the greatest “reading time” displayed or presented at the top of the list.

FIG. 2 is a diagram illustrating components of a system of the present disclosure in one embodiment for prioritizing online comments on social network web page. A processor 202 may include a central processing unit (CPU) or another hardware processor. A memory 204 is coupled to the processor. A user may interact with a social network application 206 via a user interface 208 associated with a social network application, for example, a browser such as a web browser. Social network content may be presented on the user interface 208. An application 210 running on the processor detect an activity of a user consuming the content presented on the user interface. The application 210 may be part of the social network application 206 or a plugin to the browser or user interface 208, or another tool, e.g., integrated with the social network application 206. The application 210 may determine time spent by the user consuming the content and store the determined time spent by the user consuming the content in the memory 204, e.g., in a data structure associated with the user. The application 210 may detect an activity of the user, determine the time spent by the user, and store the determined time spent for each of a plurality of users, who for example views the content and comments on the comment.

The application 210 may index the plurality of users' time spent consuming the content. Responsive to the user entering a comment on the content, the application 210 may determine the depth of consumption of the content by the user based on the determined time spent by the user consuming the content. The application 210 may also rank the comment entered by the user among a plurality of comments entered by one or more of the plurality of users based on the depth of consumption. The application may further present the comment entered by the user on the user interface 208 in the order of the ranking.

An embodiment of the system and/or method of the present disclosure as described above uses a user's prior time spent on content to predict future interest in content and change notification or delivery of news, or use this information to gauge the value of a user's contributions with respect to content they have spent time on. The promotion of a first user's posts to other second users may be changed based on the first user's time or depth of consumption of the content. In one aspect, prioritization of social network notifications for other users may be based on the “amount of time spent on content”.
